Robert has more: Tiberius's Villas on Capri
The emperor Tiberius left Rome in 26 AD never to return. For most of the rest of his life he stayed on the island of Capri, where he had 12 villas. Remains still exist of some of them. The best preserved of them is the Villa Jovis, or possibly Jonis, which was the largest. CapriWeb has four pages of text and some nice pics of the Villa Jovis, while Oebalus also has informative text and a floor plan. read on
